Description

The remote Windows host is running a version of the Microsoft .NET Framework that is affected by multiple vulnerabilities :

  • A spoofing vulnerability exists that could allow an attacker to modify the contents of an XML file without invalidating the signature associated with the file. (CVE-2013-1336)

  • An authentication bypass vulnerability exists because of the way the Microsoft .NET framework improperly creates policy requirements for authentication when setting up WCF endpoint authentication. A remote attacker who exploited this vulnerability may be able to steal information or take actions in the context of an authenticated user. (CVE-2013-1337)
